commit https://github.com/vim/vim/commit/8767f52fbfd4f053ce00a978227c95f1d7d323fe
Author: Bram Moolenaar <Bram@vim.org>
Date: Fri Jul 1 17:17:39 2016 +0200
patch 7.4.1975
Problem: On MS-Windows large files (> 2Gbyte) cause problems.
Solution: Use "off_T" instead of "off_t". Use "stat_T" instead of "struct
stat". Use 64 bit system functions if available. (Ken Takata)
